Definitions

  • the present invention relates to a method for producing a composite in which a porous fiber-reinforced thermoplastic resin sheet is bonded to part or all of one or both surfaces of a resin molded article.
  • porous fiber-reinforced mature plastic resin sheet is lightweight and has excellent strength, it is widely used as soundproofing materials such as engine covers for vehicles, heat insulating materials, exterior materials, exterior materials for home appliances, building materials, etc. Have been.
  • Such a porous fiber-reinforced thermoplastic resin sheet is usually used as a composite in combination with a resin molded body for attachment to other members.
  • Such a composite is usually produced by molding a resin molded body and a porous fiber-reinforced thermoplastic resin sheet as base materials into desired shapes, respectively, and then joining them together with an adhesive or the like.
  • a molding die for the resin molding and a molding die for the porous fiber-reinforced thermoplastic resin sheet are required, and the process becomes longer. It was not sufficient in terms of process and cost. Further, in the case of bonding with an adhesive, there is a problem that the resin sheet is easily peeled off from the base material due to the deterioration of the adhesive. Disclosure of the invention
  • An object of the present invention is to provide a composite formed by laminating a porous fiber-reinforced thermoplastic resin sheet on part or all of one or both surfaces of a resin molded article, without using an adhesive or the like.
  • An object of the present invention is to provide a method for easily and efficiently integrating and manufacturing.
  • the method for producing the composite of the present invention comprises:
  • the first porous fiber-reinforced thermoplastic resin sheet is disposed between the resin molded body and the first mold.
  • the resin molded article according to the present invention may have at least one thermoplastic resin pin-like projection on each of both surfaces thereof.
  • the resin molded article is softened by heating. It is preferable that the method further includes a step of disposing the second porous fiber-reinforced thermoplastic resin sheet between the resin molded body and the second mold.
  • the force caused by the expansion of the porous fiber-reinforced thermoplastic resin itself is applied to the outer peripheral surface of the pin-shaped projection inserted into the porous fiber-reinforced thermoplastic resin sheet.
  • Restoring force acts, so that sufficient bonding strength is obtained, and the resin molded body and the resin sheet are reliably integrated via the pin-shaped projections.
  • a first concave portion into which at least a tip end of the pin-shaped projection can be inserted when the mold is clamped is formed in a portion of the mold facing the pin-shaped projection.
  • the distance between the outer peripheral surface of the pin-shaped protrusion and the inner wall surface of the first concave portion in the mold-clamped state is 0.2 to 1 Om. It is preferably in the range of m.
  • the first pedestal is formed at a portion of the mold facing the pin-shaped protrusion and has a cross section larger than a bottom area of the first recess and a desired height. May be provided.
  • the length of the pin-shaped protrusion is equal to or longer than the thickness of the resin sheet before molding, and the pin-shaped protrusion is pierced by penetrating the resin sheet.
  • the tip of the pin-shaped projection may be pressed.
  • a first shear surface composed of a surface substantially parallel to a clamping direction of the first mold and the second mold is formed on a part of the surface of the resin molded body.
  • a second shear plane corresponding to the first shear plane may be formed on a part of the surface of the mold.
  • a part of the resin sheet includes a portion including the first shear surface of the resin molded body and a second shear. It will be cut by the surface. More specifically, by bringing at least a part of the first shear surface into contact with at least a part of the second shear surface, or including the first shear surface of the resin molded body.
